# Application Versioning
When you need to update your previously uploaded Application build version by keeping your Stream link and application configurations the same without the need to create a new Stream link each time, you can use the Application Versions feature to upload new versions for an existing application.
You can easily switch between the versions you've uploaded with just a few clicks, and upload new versions for an existing app.
When you upload a new build, it will be automatically assigned as the **Active** version and all your existing Streams will be updated to use this version. If you need to switch back to a previous version, you can also activate it from the same window.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.vagon.io/streams/configurations/application-versioning.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
